<h3>
Answer: 24</h3>
=========================================
Work Shown:
f(x) = x^2 - 2x
f(2) = 2^2 - 2*2 ... replace every x with 2
f(2) = 4 - 4
f(2) = 0
----------------------------
g(x) = 12-8x
g(3) = 12-8*3 ... replace every x with 3
g(3) = 12-24
g(3) = -24
----------------------------
Subtract the results of the previous two sections
f(2) - g(3) = 0 - (-24)
f(2) - g(3) = 0 + 24
f(2) - g(3) = 24
Given,
- Side of the octagon = ( 2a + 1 ) units
» Perimeter means total length of its boundary.
→ Octagon has 8 sides.
So,
→ Perimeter of Octagon = Length of 8 sides
→ Perimeter of Octagon = 8 ( 2a + 1 ) units
→ Perimeter of Octagon = 16a + 8 units
Therefore,
- Perimeter of the octagon is
units.
Answer:
She pays $1060 for the phone.
Step-by-step explanation:
Deposit = $100
She pays $80 each month for a year. $80 x 12 = $960. Then we need to add the deposit with the monthly instalments to find the total. $100 + $960 = $1060
Total:
$1060
4*5 is 20
add 2 zeroes to the end because of the two you took out from 40 and 50
40*50=2000
Answer:
33 material
Step-by-step explanation:
A simple proportions problem.
9:3 = 3:1
so it takes 3 yards to make 1 window
We multiply both sides by 11 to get
33:11 which now we get 33 material
